To find the value for \( \hat{y} \) (the predicted weight) using the equation of the line of best fit, you can substitute \( x \) (the age) into the equation \( \hat{y} = 5.5x + 16 \).
Given that the age \( x \) is 8:
\[ \hat{y} = 5.5(8) + 16 \] \[ \hat{y} = 44 + 16 \] \[ \hat{y} = 60 \]
So, the predicted value \( \hat{y} \) is 60.
The correct response is:
60
